Synopsis

Ruthless assassin Genji has become bored with his current life and wishes to retire from a life of crime. The only problem is the League of Assasins that is reluctant to let someone so skilled leave. After some negotiations, the League agrees to let Genji leave after one final mission. What Genji didn't realize was that no one had left the organization alive. Betrayed at the last moment, Genji was left for dead. Unwilling to let everything end like this, he enters into an agreement with a supernatural force. Now he has to enter different worlds to complete the assigned missions or face the consequences.
